SNOW is a utility for concealing messages in ASCII text by appending whitespace to the end of lines. Because spaces and tabs are generally not visible in text viewers, messages concealed with whitespace are effectively hidden from casual observers. If SNOW's built-in encryption is used, the message cannot be read even if it is detected. SNOW exploits the Steganographic Nature Of Whitespace, similar to finding a polar bear in a snowstorm; hence the name.
METAXPON ("Metachron" in Greek letters) is a small and fast audio DSP library for time-scale manipulation of 16-bit integer or 32-bit floating point stereo audio data streams. It employs a rigid phase-locked vocoder with dedicated transient detection and processing, and can work in real-time or non-real-time. Four editions are included - a portable edition and three x86 editions. The portable edition can be built with any ANSI C compiler and is OS- and architecture-independent. The three x86 editions are written in assembly using the FPU, 3DNow!, and SSE instruction sets, respectively, with automatic selection between them depending on the CPU capabilities. They can be compiled with MASM, JWASM, or NASM, producing libraries of object files in 8 formats.
SYINF shows in brief a system's CPU brand and model, RAM size, disk space, operating system, regional parameters, and current date and time. It can run in interactive (menu) or batch mode. There are two versions, in the C and C++ languages. They have been tested on 20 (15) compilers, 26 (25) operating systems, and 18 architectures. (Figures in parentheses are for the C++ version.) Both versions are conveyed in source code form only, each as a single ~35 KB source text file.
ucpp is a C preprocessor. It is designed to be quick and light, but still fully compliant to the ISO standard 9899:1999, also known as C99. ucpp can be compiled as a stand-alone program or linked to some other code; in the latter case, ucpp will output tokens, one at a time, on demand, as an integrated lexer. ucpp operates in two modes: in lexer mode, ucpp is linked to some other code and outputs a stream of tokens where each call to the lex() function will yield one token; in non-lexer mode, ucpp preprocesses text and outputs the resulting text to a file descriptor. If linked to some other code, the cpp() function must be called repeatedly, otherwise ucpp is a stand-alone binary.
TAP4Pascal is an easy-to-use but powerful unit testing suite for Pascal (FreePascal, Turbo Pascal, et al.), conforming to the Test-Anything Protocol (TAP) specification, originally developed for testing Perl, and lightweight enough to work on any platform since it is entirely text-based. It comes with its own test harness for running and summarizing the results of multiple test sets. It aims to be straightforward and to make test building easy and quick for developers, and to help software work better for everyone.
